Version history
The AMD FidelityFX™ SDK 1.1.4 is a patch release that includes additions to API and fixes for issues discovered with AMD FSR 3.1.0 to 3.1.3.
Exposed 4 new tunings to reduce AMD FSR upscaler ghosting in newly disoccludded pixels or highly reactive pixels.
Changed the default value of
fMinDisocclusionAccumulationto-0.333(from equivalent of0.333in AMD FSR 3.1.3) to reduce disocclusion ghosting.Added
ffxQueryGetProviderVersionto get version info from created ffx-api context.Exposed
ffxDispatchDescFrameGenerationPrepareCameraInfoas a linked struct. It is a required input to AMD FSR 3.1.4 and onwards for best quality.Added frame generation debug checker support.
Dropped unused interpolation command lists if frame generation callback fails, to fix infinite wait at swapchain destruction.
General fixes to Vulkan® Frame Interpolation Swapchain.
General framework fixes and updates.
Frame pacing debug line added to Vulkan®.
Added new FFX error when create frame interpolation swapchain results in
E_ACCESSDENIEDin DX12 due to overlay or capture software.Enabled support for frame interpolation swapchain on Windows® 10 1909 and potentially earlier versions.
Fixed flipped disocclusion factor from previous and current backbuffer.
Fixed HDR mode issues in Cauldron sample.
Fixed MSVC C compile errors including ffx-api.
